The magnetic field due to a 2-a current flowing in a long, straight wire is 8 μt at a point p, a certain distance away from the wire. how far is this point from the center of the wire?

Distance from the center of wire is 0.05 meters.

Explanation:

It is given that,

Current flowing in the wire, I = 2 A

Magnetic field,

Let d is the distance from the center of the wire. The magnetic field at a distance d from the wire is given by :

d = 0.05 meters

So, the distance from the wire is 0.05 meters. Hence, this is the required solution.

when insulating materials rub against each other, they may become electrically charged . electrons , which are negatively charged, may be 'rubbed off' one material and on to the other. the material that gains electrons becomes negatively charged. the material that loses electrons is left with a positive charge.
